FIG 07 — FAQ

Frequently asked questions

Common questions about Art of Code and how it works

Art of Code is the den of devs: a developer destination featuring true stories of builders who made it on their own terms, free browser-based tools (JSON formatter, CSS generators, file converters), coding games with leaderboards, a digital shop, and a curated job board. The tools and games are free and need no account.

Reading stories, using the tools, playing the games and browsing jobs all cost nothing, with no subscription and no paid tier. Some things are paid: the shop sells digital products, posting a job uses credits, and sponsor slots are bought. Nothing you need in order to read, browse or use a tool is behind a payment.

Not for most of it. Every tool, every game and the whole blog and job board work straight away with no account. You only need one to save posts, apply to a job, publish on the blog, post a job or buy from the shop.

The tools run in your browser, so the files and text you put into them are processed on your own device and are not uploaded. The one exception is the YouTube thumbnail downloader, which has to send the video ID to fetch the image.

There are over 50, all free: formatters and validators like the JSON Formatter, converters for PDF, Excel, CSV and images, generators for gradients, box shadows, hashes and UUIDs, and small everyday things like a Pomodoro timer and a daily todo.

Yes, all Art of Code tools are responsive and work on mobile devices, tablets, and desktop computers.

Not in the FreeCodeCamp sense. Art of Code runs live courses, but it is not a self-paced curriculum site. Mostly it is a den for developers: a place to read true stories of misfit builders, use free browser tools, play coding games, and find curated jobs.

Almost never. The tools work in your browser and the files you open in them stay on your device. The YouTube thumbnail downloader is the exception, because it has to look the video up.

Yes. Companies post their own roles and the board is curated, with company profiles verified before they are shown as verified. Listings can be taken down if they do not hold up.

No, Art of Code is not a SaaS (Software as a Service) product. It is a free web platform. Tools are browser-based utilities, not subscription software, and there are no subscriptions of any kind.

No, Art of Code is not open source. The platform code is proprietary. However, all tools are free to use without restrictions.

Tool data is not. It is kept in your browser's local storage, so each browser keeps its own and nothing is synced between them. Things tied to an account, such as saved posts and job applications, do follow you once you sign in.

Art of Code is built and maintained by MadMVP (madmvp.com), a software development agency specializing in building MVPs, EdTech platforms, and digital products for startups.

Art of Code Summary

Art of Code is the den of devs: a developer destination featuring true stories of builders who made it on their own terms, free browser-based tools, coding games, a digital shop, and a curated job board. The tools run in the browser, so the files you open in them stay on your device. The platform offers over 50 free developer tools including JSON Formatter, Gradient Generator, CSV to Excel converter, and productivity utilities. Visit the den at artofcode.in.
